UTSW Releases First Atomic Structure From its Cryo-EM Facility

UT Southwestern Medical Center researchers have published a 3-D atomic structure of the ion channel found in mammals that is implicated in a rare, inherited neurodegenerative disease in humans. The work marks the first such structure determined using the university’s $17 million cryo-electron microscopy (cryo-EM) facility.

Novel Lenses Enable X-ray Microscopy with Record Resolution

Researchers at DESY have reported the creation of novel lenses that enable X-ray microscopy with record resolution. The new lenses consist of over 10,000 alternating layers of a new material combination—tungsten carbide and silicon carbide—that allowed the team to achieve a focus spot size with a diameter of less than...

ICC20 Accepting Abstracts for 2018 Conference

Abstract submission is now open for the 20th International Cryocooler Conference (ICC20), the premier global gathering on cryocooler technology. The meeting will feature oral and poster presentation sessions, plus CSA's Foundations of Cryocoolers short course.

Physicists Develop Faster Method to Create Bose-Einstein Condensates

MIT physicists have improved the cooling techniques used to cool atoms into Bose-Einstein condensates. The new method is faster than the conventional one and conserves a large fraction of the original atoms.

A New, Cold Window into Electron Behavior

Physicists at MIT and Princeton University have developed a technique that can peer deep beneath the surface of a material to identify the energies and momenta of electrons there.

Linde Lifts Macy’s Thanksgiving Day Parade Balloons High

The iconic Macy’s Thanksgiving Day Parade balloons once again soared above the streets of New York City thanks to helium supplied by Linde North America, Inc. Linde supplied some 300,000 cubic feet of helium to the parade this year, the 23rd consecutive year of its partnership with Macy’s.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium?

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
